Best Buy Co Inc's retail website is back online after it was down for a second time on Black Friday, the busiest U.S. shopping day in terms of sales and traffic since 2005, according to ShopperTrak.

"A concentrated spike in mobile traffic triggered issues that led us to shut down BestBuy.com in order to take proactive measures to restore full performance," the company said in a statement on its corporate website.
